Thunderbird's calendaring and scheduling add-on "Lightning"

The release of a new Mozilla type calendar software was announced.

Currently, let's make calendar software based on Mozilla! There are three major projects.

1. Calendar
2. Sunbird
3. Lightning

Since "Calendar" and "Sunbird" have been around for a long time, there are also a lot of people who know it.

Although it is good to be in compliance with the standard, it is a stage that it is fragile, data garbled, there are many bad characters, and so on regarding practical use, but the third calendar application Is "Lightning".

All the code itself is based on the same thing, but the feature is to cooperate with the email software Thunderbird. It will let me know as an email if there is a schedule. Moreover, it can capture the schedule written in the e-mail as it is. Indeed, "Outlook" which is in the office as the schedule management software has a section that puts considerable importance on coordination between schedule management and e-mail, each day has a daily schedule, and it is very compatible in terms of the software that keeps using every day It should be good. However, it is now that the type of schedule management software, such as "this is it!", Calendar software has not appeared.

I would like you to reach a level that can withstand practical use somehow ...
